I replaced my screen with LCD and after putting my LG Stylo 3 (not plus) back 2gether my volume BUTTON doesn’t work & it doesn’t protrude from the side of my phone anymore. I went into my settings to adjust the volume that way also but that didn’t do anything? I am pretty sure I didn’t damage my speaker when I put my phone back together? I wonder if there’s some kind of connection from my speaker to my physical volume button that I didn’t put back together correctly or if there’s a small piece that goes under my physical volume button that I lost while taking my phone apart? If anyone can help I’d really appreciate it?
no so sure about having any connection between the hard-keys to the speaker.. I will recommend disassembling phone again and observe all contacts and connections then reassembly it carefully.
